[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] As described in the background section, traditional silica sand preparation devices often use manual or simple mechanical methods for feeding, which has many shortcomings. On the one hand, manual feeding makes it difficult to ensure the accuracy of the feeding amount, which can easily lead to excessive or insufficient material. On the other hand, simple mechanical feeding devices lack precise quantitative control.

[0028] To solve this technical problem, this utility model provides a silica sand preparation device with a quantitative feeding structure.

[0029] For details, please refer to Figures 1-5 The silica sand preparation device with a quantitative feeding structure specifically includes:

[0030] The crusher 1 and the support platform 2 are set on one side of the crusher 1. A weighing sensor 201 is installed on the top of the support platform 2. A weighing plate 202 is installed on the top of the weighing sensor 201. A material frame 203 is placed on the top of the weighing plate 202. The material frame 203 is equipped with a drive unit. The weighing sensor 201 and the weighing plate 202 cooperate with each other to weigh the material. The drive unit and the material frame 203 cooperate to transport the weighed material to the crusher 1.

[0031] The silica sand preparation device with a quantitative feeding structure provided by this utility model calculates the amount of material by weighing, ensuring the accuracy of each feeding, reducing the error caused by manual feeding or simple mechanical feeding, and improving the stability and consistency of the product.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] Example 1, please refer to Figures 1-5 A silica sand preparation device with a quantitative feeding structure includes a crusher 1 and a support platform 2 disposed on one side of the crusher 1. A weighing sensor 201 is installed on the top of the support platform 2, a weighing plate 202 is installed on the top of the weighing sensor 201, and a material frame 203 is placed on the top of the weighing plate 202. The material frame 203 is provided with a driving unit. The weighing sensor 201 and the weighing plate 202 cooperate with each other to weigh the material, and the driving unit and the material frame 203 cooperate to transport the weighed material to the crusher 1. This application calculates the amount of material by weighing, ensuring the accuracy of each feeding, reducing the error caused by manual feeding or simple mechanical feeding, and improving the stability and consistency of the product.

[0036] Furthermore, such as Figures 1-2 As shown, the drive unit includes a connecting frame 204 sleeved on the outer surface of the material frame 203. Hydraulic cylinders 205 are connected to both sides of the connecting frame 204. A support member is provided between the two hydraulic cylinders 205 and the support platform 2. The hydraulic cylinders 205 can push the material frame 203 to move through the connecting frame 204, thereby enabling the material frame 203 to transport the material to the crusher 1.

[0037] Furthermore, such as Figure 1 As shown, the support includes a support base 207 mounted on the top of the support platform 2. Support rods 206 are mounted on both sides of the support base 207. The two support rods 206 are respectively connected to two hydraulic cylinders 205. The support rods 206 and the support base 207 cooperate with each other to support the hydraulic cylinders 205.

[0038] Furthermore, a gap is left between the inner wall of the connecting frame 204 and the outer surface of the material frame 203, and a gap is also left between the top of the connecting frame 204 and the material throwing frame 203, so that the connecting frame 204 does not come into contact with the material frame 203 during the weighing process, so as not to affect the weighing.

[0039] Example 2 further optimizes the silica sand preparation device with a quantitative feeding structure provided in Example 1. Specifically, as follows: Figure 4As shown, an inclined plate 208 is provided inside the material frame 203. The inclined plate 208 is located on the inner wall of the material frame 203 away from the crusher 1. The top of the inclined plate 208 is inclined so that the material in the material frame 203 can move towards the crusher 1 when feeding.

[0040] Furthermore, such as Figure 3 and Figure 4 As shown, a scraper 212 is provided on the top of the weighing plate 202. A connecting piece is provided between the scraper 212 and the material frame 203. The scraper 212 can push the material remaining on the top of the weighing plate 202 toward the crusher 1. A slope is provided on the top of the weighing plate 202 near the crusher 1. The gap between the top of the connecting frame 204 and the material frame 203 is smaller than the thickness of the weighing plate 202. This arrangement allows the material frame 203 to return to the top of the weighing plate 202 under the guidance of the slope when it moves from the top of the crusher 1 toward the support seat 207. After returning to the top of the weighing plate 202, its height increases slightly to leave a gap with the connecting frame 204.

[0041] Furthermore, such as Figure 4 As shown, the connector includes a connecting frame 211 mounted on the top of the scraper 212. The connecting frame 211 is connected to the material frame 203 by bolts. The scraper 212 can be installed by the cooperation of the connecting frame 211 and the connecting seat 210.

[0042] Example 3 further optimizes the silica sand preparation device with a quantitative feeding structure provided in Example 1 or 2, specifically, as follows: Figure 1 As shown, a hopper 101 is installed on the top of the crusher 1, and the hopper 101 is designed to facilitate the entry of materials into the crusher 1.

[0043] Furthermore, such as Figure 1 As shown, a guide plate 209 is installed on one side of the top of the support platform 2. The guide plate 209 is located below the weighing plate 202, and one end of the guide plate 209 extends into the hopper 101. The guide plate 209 facilitates the guidance of the material on the top of the weighing plate 202 to the hopper 101.

[0044] Furthermore, the weighing sensor 201 is connected to a controller, and the hydraulic cylinder 205 is connected to a control valve. The control valve is connected to the hydraulic station, which has a beneficial effect. The controller can be a PLC controller. The controller receives the signal from the weighing sensor 201. When the material weight reaches the preset value, the controller sends a command to the hydraulic station. The control valve adjusts the extension and retraction stroke of the hydraulic cylinder 205, driving the material frame 203 to move towards the crusher.

[0045] The usage process of the silica sand preparation device with quantitative feeding structure provided by this utility model is as follows:

[0046] Before feeding, the load cell 201 detects the weight of the weighing plate 202, the material frame 203, the connecting frame 211, the connecting seat 210, and the scraper 212, i.e., the unloaded weight, which is used as the starting weight. Material is added into the material frame 203 and onto the top of the weighing plate 202. During the feeding process, the load cell 201 weighs the material. When the weight of the material reaches the target weight, feeding stops, and the hydraulic cylinder 205 pushes the material frame 203 towards the hopper 101 through the connecting frame 204. The material is pushed to the hopper 101 by the material frame 203. During this process, the material first falls into the guide plate 209 and then into the hopper 101. After the scraper 212 separates from the weighing plate 202, the material feeding is completed. Then, the hydraulic cylinder 205 drives the material frame 203 back to the top of the weighing plate 202 through the connecting frame 204. After the material frame 203 is reset, the hydraulic cylinder 205 extends a little further so that the connecting frame 204 and the material frame 203 do not contact each other.
